A-S Galleria Toilet, Model 2014.013
So I came back to the city from Long Island and heard the persnickety AS "Galleria" toilet in my NY apartment ghost-flushing. Left it a while because I had a few things to do, and finally my brain said, "Go fix the thing." I figured it was just that the flapper was hung open again on the Rube Goldberg-like pushbutton flush thingy and all I had to do was jiggle the button. To my surprise, when I pushed the button, I could feel the flapper lift and the thing flushed, despite all the water that was already running into it.
Pulled the cover and realized that I had a runaway fill valve. The reason was obvious. The rod to the ball had snapped its holder on the fill-valve top, so no pressure to push down on the plunger and shut off the water. The plastic had just cracked and failed right around the pivot-rivet. Fortunately, the overflow riser was of sufficient diameter to take everything the ballcock was throwing at it, and the tank didn't overflow. I had been gone for the better part of a day. What a mess that would have been.
So now the problem. I had previously looked at replacement ballcocks for the thing, as American Standard no longer makes the OEM ballcock, which has a variable diverter attached; it varies the amount of refill water depending upon the stage of the refill, as measured by the level of water in the tank. I knew that probably-will-work valves from Lasco, Kohler, etc., cost anywhere from $35 to $120 from various plumbing supply places, and that the 1B1X top sometimes could be made to fit, and the top is sometimes sold separately.
Since it was 12:15 in the morning, I knew I had only one chance to fix it tonight. Off I went to the fabulously-odd "Nuthouse" hardware store on 29th Street in Manhattan, the only real hardware store in the City open 24 hours. They have 5 floors of pretty-much everything -- and I mean everything, like stuff that's been sitting in there for 30 years. Someone has to go with you if you want anything other than the limited assortment of regular stuff on the main floor, and the guy at the register wasn't going to be a promising helper. Fortunately, the plumbing guy was just getting off, and he was so incredibly nice to, on his own time, wade into their marginally-organized plumbing section in the basement with me. He understood exactly what I was looking for, unlike the guy at the register. After 30 minutes of searching ("I know I have it; I just don't remember where I put it"), we were able to find a non-diverter Coast 1B1X knockoff by Wal-Rich, made for the Rialto. I figured I would just bite the bullet and pay for the whole valve, then remove the top and just use that. Judging from the prices I had seen online, and knowing that Nuthouse wasn't a discount place, I was figuring $50, but I was happy not to have the toilet non-functional until the maintenance guys returned on Tuesday (this being Memorial Day Weekend).
At checkout -- $9. Nine. Dollars. Holy crap. I asked the guy to double-check because I didn't want to be ripping off these nice people. Yep. Nine bucks.
When I got it home, I disassembled it and popped the top and the plunger into the old valve body. Sadly, the holes wouldn't line up. The old valve was just a smidge wider in diameter than the top of the new one, so although the holes were at the right place on the ring, the screws wouldn't go in. I had heard about this somewhere before -- that even though they are technically supposed to be identical, sometimes they aren't. That was the case here with my $9 Wal-Rich knockoff of the Coast. So I put the new thing back together and swapped the valves. That was the easiest part -- couldn't have been simpler. (I had to use the old rod and ball, because the ball is a special size and the standard rod that came with the valve was too long for this compact toilet.)
I used the refill hose from the new valve, which is comparable to the original, and just shoved it into the hole in the porcelain where the old hose went from the diverter. (The refill hose on these valves is of significantly-larger OD and ID than on, say, a Korky 528.)
And here is why I am posting: I was very concerned that a valve just with a static (albeit adjustable) refill wouldn't work on the Galleria -- that there was something important about the variable refill that really made a difference in the toilet's performance.
Turns out that the $9 Wal-Rich ballcock with no variable diverter works PERFECTLY. I played with the refill percentage a bit to avoid wasting water. On this valve, you adjust how much goes into the tank and the rest is refill. Turns out that wide-open into the tank is the optimal setting.
Had I known I could use a reasonably-priced 1B1X knockoff with no diverter, I would have chucked the hissy, leaky, troublesome OE valve years ago, and replaced it with a diverterless one.
So...if anyone with a one-of-a-kind AS Galleria toilet happens to run across this thread, just get yourself a non-diverter 1B1X-style valve, for whatever good price you can find, and swap away without concern or regret.
